Step 303: 259720 + 860 = 260580
Step 304: 260580 + 860 = 261440
Step 305: 261440 + 860 = 262300
Step 306: 262300 + 860 = 263160
Step 307: 263160 + 860 = 264020
Step 308: 264020 + 860 = 264880
Step 309: 264880 + 860 = 265740
Step 310: 265740 + 860 = 266600
Step 311: 266600 + 860 = 267460
Step 312: 267460 + 860 = 268320
Step 313: 268320 + 860 = 269180
Step 314: 269180 + 860 = 270040
Step 315: 270040 + 860 = 270900
Step 316: 270900 + 860 = 271760
Step 317: 271760 + 860 = 272620
Step 318: 272620 + 860 = 273480
Step 319: 273480 + 860 = 274340
Step 320: 274340 + 860 = 275200

So, 860*320 = 275200
